How does it work?
Google AdMob helps you monetize your mobile app through in-app advertising. Ads can bedisplayed using various format options which are seamlessly added to platformnative UI components. On Android, you can additionally display in-app purchaseads, allowing users to purchase advertised products from within your app.
Banner | Interstitial | Native | Rewarded |
To display ads, you'll need anAdMob-registered app that integrates theGoogle Mobile Ads SDK (iOS |Android). You can then activate one or moreAd Unit IDs which are unique identifiers for the places in your app to displayads.
TheMobile Ads SDK helps you gain insights about your users, drivemore in-app purchases, and maximize ad revenue. To do all this, the defaultintegration of the SDK collects device information, publisher-provided locationinformation, and general in-app purchase information (such as item purchaseprice and currency).
User metrics, Firebase, andGoogle Analytics
To make informed decisions about optimizing your app's user experience and yourad revenue, you'll need metrics and data from your app. Working together,AdMob, Firebase, andGoogle Analytics offer additional levels ofconfiguration to help you achieve your optimization goals.
